What is the Difference Between Air and Oxygen? The air that people breathe is a mixture that contains primarily oxygen and nitrogen. The nitrogen generally makes up approximately 78%, while oxygen makes up 21%. Other gases, including carbon dioxide, hydrogen, helium, argon, and neon, make up the remainder. These gases dissolve and are carried in the blood.

Your 14 Most Common Questions About Oxygen and Answers from Lung Experts We can’t live without it. The air we breathe is approximately 21% oxygen. When a patient is started on supplemental oxygen they are often put on something in the range of 24 to 30% oxygen, so it is just a little more than is in the usual air you breathe.

Facts About Oxygen Breathe in … breathe out. Ahh. Hooray for oxygen, the element that keeps much of life on Earth humming. Element No. 8 on the Periodic Table of the Elements is a colorless gas that makes up 21 percent of Earth's atmosphere. Because it's all around, oxygen is easy to dismiss as dull and inert; in fact, it's the most reactive of the non-metallic elements.

- Without it, we would die within minutes. Pure air is a mixture of several gases that are invisible and odourless. It consists of about 78% nitrogen, 21% oxygen, and less than 1% of argon, carbon dioxide, and other gases — as well as varying amounts of water vapour.

Altitude-Oxygen Chart Use the tables below to see how the effective amount of oxygen in the air varies at different altitudes. Although air contains 20.9% oxygen at all altitudes, lower air pressure at high altitude makes it feel like there is a lower percentage of oxygen.

- One mole of any substance contains 6.02 x 1023… particles (similar to how a dozen is 12 of anything). Air is about 21% oxygen, depending upon your location and local biotic and abiotic factors. So, at STP, 1 liter of air is about 0.21 liters of oxygen. To find out how many moles that represents, divide 0.21 by 22.4. Take that answer and multiply by 6.02 x 1023. It should be a very large number, on the order of 1021.

Air - Composition and Molecular Weight Dry air is a mechanical mixture of nitrogen, oxygen, carbon dioxide and more. Air is a mixture of gases - 78% nitrogen and 21% oxygen-with traces of water vapor, carbon dioxide, argon, and various other components. Air is usually modeled as a uniform (no variation or fluctuation) gas with properties averaged from the individual components. 1  The water or vapor content in air varies.

- How many percent of oxygen and carbon dioxide in the atmosphere? The atmosphere is about 20% oxygen, about 79% nitrogen, about 1% Argon, and a fraction of a per cent of a number of other gases, including 400 ppm (parts per million) of carbo…n dioxide. One per cent is 10,000 ppm, so 400 ppm is less then 1%.

- Air at sea level contains about 79 percent nitrogen and 21 percent oxygen. Very little carbon dioxide is present — only about 0.04 percent. As the body needs to take in oxygen and exhale carbon dioxide, however, exhaled air has a different composition.ompared to the low levels of about 0.04 percent in inspired air, exhaled air contains a hundred times more CO2, at 4 percent content.
